If we get clear skies just before 7pm on Wednesday (25-Apr), there's a chance of spotting the ISS in daylight, as it passes in front of the Moon.The Space Station should be bright enough to see in daylight, so long as you know exactly where and when to look - so point your binoculars at the Moon at four minutes to seven and have a go. But be careful where you're pointing, since the Sun will still be above the horizon - it's best to stand somewhere where you're shaded from it. And don't blink, as it will zip through your field of view in a couple of seconds!

If you're watching from the North side of Bury or Bolton, or to the South of Chorley, then you should see it transit across the unlit part of the lunar disk, but if you're North or South of this line it will appear below or above the Moon in the sky.

That's amazing Ross. You certainly are an wonderful source of information. I shall be in Barnsley on Wednesday, celebrating my grandaughter's 18th Birthday so I shall have to get my atlas out and triangulate Barnsley with Bury, Bolton and Chorley but I am sure the view will be even more spactacular from God's own County.

This is the predicted region of visibility for tomorrow evening's event:

From any points on the blue line the ISS transits across the lunar equator, but outside the red lines it will "miss" the lunar disk entirely. This is just the local section of a "stripe" around the Earth's surface, so the event will also be visible from parts of West Yorkshire too (but not the Scottish Borders!)
